At Hidden line Below pipe not visible

[Anonymous]

when I change wireframe to Hidden line at the crossing pipe, below pipe is not visible. I also checked the mechanical settings and other basic things. See the snap shot I attached.

2 locations to confirm

1.Mechanical Settings and

2.Line Styles under Additional Settings

the assigned Line style in one setting may be different in the other.

in this example "Hidden Lines" is assigned to Dashed in Line Styles.

so depending on the line pattern being used in the line style - the dash and space may be to large to display correctly in your view.

other things to consider - level of detail being used, and the Beyond Linestyle assigned
